To all whom it may concern Be it known that we, HOWARD S. PAINE 'and J OHN HAMILTEJN, citizens of the United States of America and employees of the Detment of Agriculture of the United tates of America, residing at Washington,

District of Columbia have jointlyjnvented lirocess for reparing Fondant o'r Chocolate Soft Cream Centers, of whichthe following is a specification. This'application is made under the act of March 3, 1883, chapter 143' (22 Stat. 625) and the. invention herein described and claimed may be used by the Government of the United States, its oflicers and employees, and by any person in the United States either in public or privatev work without payment to us of any royalty thereon.

in the art of manufacturing fondant or chocolate soft cream centers, the customary practice is to add a certain proportion of commercial glucose, invert sugar, honey or other saccharine substance at some time during the candy making process to prevent too rap-id crystallization of sucrose and resulting formation of coarse or large crystals. The product obtained in this way possesses a smooth or soft consistency rather than the coarse, granular texture characteristic of vfondant which has grained too rapidly. Owing to the fact, however, that it is considered the best commercial practice to mold confectionery of this nature before coating with chocolate or other material, it is only possible to add as much glucose or invert sugar as will permit of satisfactory molding. It is sometimes desired to produce a soft center having the appearance of being partially liquefied, and for this purpose sufficient glucose or invert sugar cannot be used to give at the same time the desired semiliquid consistency and-a soft cream which can be satisfactorily molded. In order to secure this semi-liquefaction, the customary commercial practice 7 is to add a small amount of tartaric acid or some other acid while the fondant is being prepared and before molding and coating withchooolate or other material. When suflicient acid has been used, a partial hydrolysis of the sugar present (sucrose) is accomplished, and it is possible in this way to make soft centers which to a. certain degree become semi-liquid consistency'on storage. This method does not" give the degree of liquefaction at tlmes desired, however, and is objectionable for the reason that when suflicient acid is used to give the necessary hydrolysis the product possesses too much of an" acid flavor. 'We have discovered that by the addition of a very small amount of a concentrated preparation of the'enzyme invertase, preferably obtained from brewers yeast but which may be obtained from other sources, it is possible tosecure the desired semi-liquid consistency without the addition of'acid. Chocolate soft cream centers prepared in this way are as fluid as are ever desired and do not possess an objectionable flavor. By using a standardized preparation of the invertase, moreover, more uniform quality may be secured and the process controlled more accurately than by other known methods.

The method is-not confined to the method of hand or machinerolling of the fondant before coating. 1 It is especiall adapted to the largescale method of can y making in which the fondant is remelted and cast in starch or otherwise molded by hand or machine before coatingwith chocolate or other material. batches of fondant at a time and subsequent ly at any later time re-melting, adding invertase, and molding In'practicing our process, we have used a commercial invertase preparation of standardized strength to make chocolate coated cream centers of varying degrees of fluidity. We have stored these creams for different periods of time and have analyzed them, proving thereby that the liquefaction This permits making up large is produced by the hydrolysis of sucrose by p the action of the'enzyme invertase.

In carrying out our process we may proceed as follows:

The fondant or soft cream is prepared in the customary commercial manner up to the is added and thoroughly mixed in, after which the cream is molded and coated with chocolate or other material in the usual man 2-4 weeks would customarily be allowed for storage, we use per l00 lbs. of granulated sugar used in making the fondant approximately 4; or 2 ounces of invertase (of such a strength that 1 gram added to 2000 cc. of a 9% sucrose solution containing 2 cc. of

" glacial acetic acidwill give suficient inversion at C. in 1 hour to reduce the reading of this solution in a, 2 decimeter tube to 23 Ventzke.). The proportion of invertase,

' however, may be greater or less than this.

Having thus described our invention, we claim:

l. A process for preparing. candy with soft cream centers, which consists of cocking a mixture of sucrose, commercial gill? cose and water to a temperature of approximately 240 F., then creaming the cooked mixture at a, temperature of approximately 90 F. to form a fondant, subsequently remelting the resulting fondant, thereafter thoroughly mixing therewith at a tempera ture of approximately 155 F. a small amount of invertase,-and finally molding said fondant and coating the same with an edible coating.

2. A process for preparing fondant or soft cream centers to hecoated with an edible coating, which includes remelting the 1&37310 fondant, and incorporating invertase there- 'with during said remelting operation.

a mixture of sucrose, a syrup essentially nonsucrose and water, to a temperature of approximately 240 F., then creaming the cooked mixture at a temperature of; approximately 90 F. to form a fondant, subsequently re-melting the resulting fondant, thereafter thoroughly; mixing therewith at a temperature of approximately 155 F. a small amount of 'invertase, and finally molding said fondant and coating-the same. with an edible coating.

a. A process for preparing candy with soft cream centers, which conslsts of boiling a mixture of four parts of sucrose, one part ofz-commercial glucose and 1% parts of water, creamimg the resulting product at a temperaturc'of approximately 90 F; to form a fondant, re-melting the fondant and thoroughly mixing therewith at a temperature of approximately 70 C. about 1/100 of a part of invertase, and finally. molding said 5on4 dant and coating the same with an edible coating.
